The most recent short interest data was recently released for the 11/15/2017 settlement date, and Medicines Co is one of the most shorted stocks of the Russell 3000, based on 17.69 "days to cover" versus the median component at 4.67. There are a number of ways to look at short data, but one metric that we find particularly useful is the "days to cover" because it considers both the total shares short and the average daily volume of shares typically traded.

Investors in Medicines Co saw new options begin trading this week, for the July 2018 expiration. One of the key data points that goes into the price an option buyer is willing to pay, is the time value, so with 241 days until expiration the newly trading contracts represent a possible opportunity for sellers of puts or calls to achieve a higher premium than would be available for the contracts with a closer expiration.
